I have a question about acid/base problem. the problem says. What is the pH of a mixture of 0.042 M of NaH2PH4 and 0.058 M of Na2HP04? Note that pKa is 6.86 So it gave the solution and said it's pH = 6.86 + log 0.058/0.042 and then it said how do we know which one is the acid or base? Just look who has more H+. SO this is where I'm confused because the Henderson Hasselbalch equation is pH...
